Hand-held Analyzer Types 2250 and 2270 – User Manual

13.1.3 Playing the Recording

Signal recordings are attached to the measurement project as annotations. The annotations icon

is displayed in the Status Field to indicate this. Tap the paperclip to open the list of

annotations. Tap the annotation to play it back – details in Chapter 3 and Chapter 6.

13.2 Logging and Enhanced Logging Software

You can use the Signal Recording facility together with the Logging and Enhanced Logging

Software. You can record the sound for the whole measurement period or you can record sound

for controlled parts of the measurement. The recordings are attached to the profile as sound

markers. The signal recordings can be controlled by the Manual Event pushbutton, the Back-

erase pushbutton, an external trigger signal, or by the level of the measured signal. You can

also control the signal recording using the stylus to mark the interesting part on the profile.

Note 1: Signal recordings can only be done during measurements.

Note 2: Signal recordings can only be done on projects saved on memory cards (or with

hardware version 4, from a USB memory stick).

13.2.1 Setting up the Analyzer

1) Select a Logging, Logging SLM or Enhanced Logging Project Template. (see section 3.3.1

for more details on templates.)

2) Depending on your memory device:

• Insert an SD memory card in a SD card slot at the bottom of the analyzer

• If you have hardware versions 1 – 3, you can insert a CF memory card in the CF card

slot at the bottom of the analyzer

• With hardware version 4, you can use a USB Type A stick at the bottom of the

analyzer

Note: You cannot record the signal on the internal disk.

3) Tap the Main Menu icon and select Explorer from the list of options. Navigate to

the memory card, create a job folder for the measurements and set the default

measurement job/path as described in Chapter 6.

4) Tap the Main Menu icon and select Setup from the list of options. Set all the parameters

as required for the Logging or Enhanced Logging measurement, see Chapter 11 or

Chapter 12, respectively.

5) Under Signal Recording you can specify the Recording Control parameters as follows:

• Automatic, if you want to start the recording when you start the measurement and stop

when you pause the measurement, and to limit the recording to Maximum Duration, if

Duration Limit is set to On

• Manual Event, if you want to start and stop the recording using the Manual Event

pushbutton during the measurement
